Lewis Hamilton warned on Saturday only a crash would prevent future repeats of the slip-streaming farce that concluded Saturday's qualifying session for the Italian Grand Prix.
The defending Formula One champion, who qualified second behind Ferrari's Charles Leclerc in his Mercedes, repeated his warning about the dangers of drivers slowing down in a bunch to find a tow.
"I am sure it is going to continue, as positioning is key. If everyone is going out so late, it will continue to be an issue in places where you particularly need a tow," said Hamilton.
"It won't be until someone crashes that they will change. We are all trying to get a gap, which continues to be key... In some places, you want a bigger gap and in some places it is about the tow.
"It is the system that needs to shift a little, but I don't think we need to start handing out penalties.
"We need to look at it and reflect and see what we can do to make it better. Better for the fans and less dangerous."
"I think most of the drivers behind wanted to pass, but didn't have the opportunity. These situations made a big mess towards the end and that's why some cars didn't make it to start their laps."
